This invention relates to a. means for maintaining textile machinery clean of foreign matter which would ordinarily settle therein during operation of the latter, and is designed primarily for use in connection with automatic spoolers and spinning frames, but it is to be understood that a means, in accordance with this invention is for use in any connection for which it may be found applicable, and the invention has for its object to provide a means for the purpose referred to so constructed and so correlated with the machine whereby an induced draft is provided through the normal openings of the machine for preventing undesirable particles, such as dust, lint and fly, generated during the operation of the machine from settling on the latter, and for delivering the same to a collector.

A further object of the invention is to provide a means having the elements thereof so constructed and so correlated with the machine to localize, relative to the latter, induced drafts whereby foreign matter such as dust, lint and fly, generated during the operation of the machine, will be drawn through the normal openings of the machine and discharged from the latter.

It is a well known fact that where a direct draft is produced by fans and directed upon textile machinery for cleaning the same, that this draft merely scatters the lint and other particles and contaminates the air in the room in which the machinery is located. Furthermore, the dust, lint and other particles which are removed from the machinery ultimately settle upon the yarn. These lint particles sometimes produce gouts when settled on the yarn which are objectionable because they reduce the quality of the cloth and hinder production by causing breaking of the yarn in the weaving process.

It is evident that by using an induction draft the air is not contaminated with these particles but instead, the particles are drawn directly into the ducts. This produces a more healthful work condition for the operators and also eliminates the dust and fly from the room which otherwise would materially afiect the quality of yarn when it has settled thereon.

It is a further object of this invention to pro vide a means for cleaning textile machinery which comprises a system of hoppers and ducts connected to a fan for creating an induction draft to clean the textile machinery, and a filltering means disposed on the other side of the fan and having one side thereof connected to the duct which discharges into the same room dated October 13, 1936, nary 16, 1936. Applica- 1937, Serial No. 140.572

from whence the air, was drawn so that the illtered air is recirculated in the same room. This has a very decided advantage, especially where thetemperature or humidity on the outside of the building is diilerent from that on the inside. 5 .For example, if the temperature on theinside of the room is 55.2 degrees higher than the temperature on the outside, then for every cubic foot of air'drawn from the outside to the inside of the room there would be required one B. t. u. to raise 10' this temperature to normal room temperature.

It is seen, therefore, that by filtering this air and recirculating the same, that the temperature of the air. is not disturbed materially, therefore, the cost of reheating this air is negligible. At the same time the humidity of the air in the mill is preserved.

It is a further object of this invention to provide an'inductlon drait for cleaning textile machinery, means for filtering said air, and means for exhausting said air in the same room and directing the exhaust upon a textile machine such as a creel to cause the lint, dust and fly from the same to be blown to suitable induction openings from whence the same is drawn again to the filtering means.

It is still a ilurther object of this invention to provide means for cleaning textile machinery by an induction draft by enclosing portions of the machinery with bellies and with the baifles so arranged as to taire advantage of gravity in collecting the fly, lint and dust on, and adjacent the said machinery and also to locate the ballles so that the centrifugal force and air currents caused hy the rotation of said machinery may be utilised for assisting in collecting the trash, fly and lint.

A system as shown and described having a .240 spindle capacity would require about 24,800 cubic feet of air per minute to he drawn therethrough in order to produce proper cleaning effects. Therefore, it is seen that if recirculation and filtering were not employed it would require continuously, approximately cs0 B. t. 11. per minute, to raise room temperature one degree F. above the outside temperature, while a difference of 30 degrees F. in outside and inside temperatures would require shout one pound of coal per minute.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which:

Figure 6 is a transverse, vertical, sectional view taken along line 6-5 in Figure '5, and

Figure 7 is a vertical, sectional detail view taken along line 1--1 in Figure 3.

Referring more specifically to the drawings, the

rality of sections such as shown in the drawings between Samsons |8 and I9 or between Samsons 20 and 2|. Extending from the opposite sides of each Samson are suitable brackets 25 and 26 having mounted on the ends thereof bobbin supply boxes 21 and 28, these boxes being shown in Figure 2, but omitted in Figure 1 in order to more clearly disclose the invention.

Secured to each side of the intermediate portions of the Samsons i8 and 2| are longitudinal channels 29 and 30 which serve as struts for rigidly tying the Samsons together. Rotatably mounted in the upper portion of the Samsons are cylinders 3| and which rotate in the direction designated by the arrows and cause the cheeses or packages of yarn 33 and 34 to likewise rotate and draw the yarn from the bobbins 35 and 35 upwardly through combs 31 and-3i respectively, to cause the same to be wound onto the packages. A suitable trackway 39 is disposed on the upper side of Samsons I8 to 2| and the end frames l6 and I1, upon which a carriage (not shown) is adapted to travel and cause empty bobbins to be replaced by a full bobbin of yarn in the spooler.

Also disposed-between each of the frames IE to 2| is a cover plate 40 and a suspended baflie 4| pivoted as at 42. On opposite sides of each Samson are upper brackets and lower brackets 46 upon which a conveyor belt 41 is adapted to travel for receiving the empty bobbins after the same have been dofied from the bobbin holders 48 and convey the bobbins to a suitable container (not shown) at-the end of the spooler.

The parts thus far described are conventional in conventional spoolers, but it is deemed necessary to disclose this much of the old structure in order to more clearly describe theinvention.

In order to use an induced draft to clean the machinery as disclosed in the drawings, it is necessary to install suitable bailles in various portions of the machineso that the draft may be directed through the natural openings of the machine to remove the dust, lint and fly there- Suitable baflles 50 and 5| have beensection of the spooler, to longitudinal struts 52 and 53 of the machine. These baiiles 5|) and 5| converge downwardly, forming an opening 54 through which the downward current of air passes together with the' dust, lint and fly from the upper portions of the machine, and particularly the dust and fly which is created by cylinders 3| and 32 and the cheese rolls 33 and 34.

While cylinders 3| and 32 do not, in themselves, create the induction draft, it is seen that since the upper side of the rolls rotate inwardly that the induction draft created by the fan, which will be presently described, will be materially assisted in collecting the fly and lint and transferring it downwardly through the opening 54.

Secured to longitudinal channels 29 and 30 are conventional baffles 56 and 51 which extend downwardly and have the lower edges thereof secured to the sides of the frames lfi to 2|. These baflies will cause the draft which passes downwardly through the bobbin boxes 58 and 59 to thoroughly cleanse the interior portions of these boxes as well as the exterior of bobbins 35 and 35. A current will also be drawn downwardly through the openings which exist between the lower edges of baflle plates 56 and 51 and the conveyor belt 41. I

Baffles 5| and 52 are secured to the upper edges of hopper 60, said baiiles SI and 62 having the upper edges thereof abutting the inside edges of bobbin supply boxes 21 and 28. The baflies 6 62 are provided by the sides of a sectional horizontally disposed rectangular frame (Figure 4) which is secured at its ends to the frames l8, 2| and at its sides to the frames I8, I9; 20* and 2|e. 'The upper portion of the frame which provides the baiiles 6|, 52 is of funnel-shaped contour in transverse section (Figure 2). The hopper in connection with that frame, which has its sides form the bailles 6|, 62, provides an open top and a closed bottom housing located about the lower portion of the sides and ends of the spooler. The hopper 60 provides the bottom of such housing. By placing the upper edges of these plates in the position shown in Figure 2, it is seen that the dust and lint from the top of the supply boxes will also be drawn downwardly into the hopper 60. Thestructure described in Figure 2 is typical of the structure in each of the sections of the spooler. In other words, the structure between Samsons 20 and 2| and the other Samsons and frames of the machine, not shown, is identical to the structure between Samsons l8 and |9 and frames l8 and I9; therefore, like reference characters will be given like parts and another description will not be made for the other sections.

Connected to the lower end of hoppers 60 are vertically disposed pipes 65 which lead into a horizontally disposed pipe 65, said pipe 66 increasing in size as it progresses to the right in Figure 1, since this pipe serves as a trunk line.

Pipe 55 leads to the intake opening of a suitable fan 61 which fan is connected to the lower side of the floor II). The pipe 66 is held in position by suitable means such as hangers 68 suspended from the lower side of floor II).

Fan 61 exhausts into a suitable duct or pipe 10 which extends upwardly through the floor Ill and leads into a filter 1| which is suspended from the ceiling l2. The filter 1| is lined with a suitable filtering material 12 such as textile fabric or wire fabric and has a suitable hinged door 13 in the lower side thereof pivoted as at 14 and thereof for directing the exhaust current of air downwardly onto the creeling apparatus which will be presently described.

A shield 'I'l encircles the filter H and causes the currents of air which pass through the filter to be directed downwardly in the direction of arrows as shown in Figures 1A and 6.

The exhaust from filter II is directed downwardly onto the creeling apparatus 80 and iii and onto the surrounding floor to cause the dust and lint particles which fall onto the floor directly beneath the creels, to be blown toward the rear of the machine. -The creels 80 and 8| have conventional fans 83 and 84 for blowing the particles from the strands of yarn as it is drawn from the creel to the warper thereby preventing it from collecting on the yarn.

After the particles are blown onto the floor, the exhaust air from the filter H blows these particles rearwardly of the creel frames to openings 85 and 88 where it is drawn by the suction produced by the fan 87 downwardly through the floor into pipes 81, 88, 89, 98 and back into pipe 68, where it is pulled through the fan 81 and forced into the filter ll. Hangers 9| are used to suspend pipes 89 and 90 from the lower side In order to cause these particles to be gathered at the openings85 and 88, a curb 92 is provided which, in the present instance in Figure 3, re-

.35 sembles a rough W in its plan view. This curb (Figure 1A) extends a slight distance above the floor level in order to properly direct these particles to the openings. The creels 80 and 8|.have a plurality of packages of yarn 93 thereon which are wound onto 'a warp beam 95 of warper 96.-

The strands leading from the packages 93 pass through comb 91, over roller 98 and then onto the warp beam. This warp beam is rotatably mounted in-arms 99 and I 08, which arms support uard rail Hil.

It is well known in the art of creeling and I -warping that movement produced by the rotation of warp beam 95 will cause all of the strands from the packages of yarn 93 'tomove rapidlyv toward the warp beam at approximately 900 yards per minute. This swift movement of the ends will cause an induced draft to be set up which will be overcome by the exhaust draft from the filtering apparatus ll, thereby, causing 5 the fly and lint which falls upon the fioor to be directed rearwardly to the openings 85 and 86 instead of, toward the warper 98.

It is also desirable to cleanse the warp beam 95 during the operation of the creeling appac0 ratus; therefore, a slotted pipe I05 has been mounted in parallel relation to the warp beam' 95 and this pipe is located with its slot I06 adjacent the surface of the warp beam. This slot I06 extends approximately the length of the warp o5 beam and collects the lint particles from the surface of the beam by virtue of .the induced draft jset up by the fan 61. The pipe "i5 is U-shaped and has each end thereof pivotally connected as at I88 and I09 to vertically disposed ducts H0 and HI respectively. These ducts lead downwardly through the floor Hi and\are connected to vertically disposed duct H2, said duct H2 having its lower end connected to pipe 90.

It is thus seen that the lint, fly, dust and other foreign particles which are created by the rota- By filtering the air and using the same over and over againin the mill, the temperature and humidity of the air is not materially affected: therefore, the air can be recirculated through the room without the necessity of drawing in outside air which is very often of different temperature and humidity from that of the room.

To draw in outside air would necessitate additional expense. 'By using an induction draft for cleaning the machinery, the particles of dust, lint and fly are collected from the room and the air is purified or conditioned. This creates a decidedly more healthful working condition for the employees as the air is purer and more free from lint and dust than it would.be if a direct cleaning machine were used, that is, cleaning machinery which does not collect any dust or lint from the machine but merely removes the lint from the machine by exposing the same to a direct blast of air.

In the drawings and specification there has been set forth a preferred embodiment of the invention, and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set-forth in the appended claims.
